the under surface thereof. The-chambers 12 thus formed extend lengthwiseof the top* or cover and'preferably in parallel relationto each otherand are open at their lower edges, opening freely into vat or tank 10.In use the lower edges of the chambers 12. dip into 'or are immersed inthe liquid electrolyte contained in the tank 10. In practice thevarious' chambers 12 should be in communi-- cation with each other. Inthe particular form shown as exemplify/ing my invention,

a duct or passage 14 is provided through the body of the top or coverand forming a communication between said chambers. Suitably suspendedthrough and within the open lower lmouth or edge of each chamber 12 isan electrode sheet or plate 15. A. convenient arrangement for suspendingthe electrode plates 15 is shown wherein rods 16 extend throughthe topor cover 11 and are welded or -otherwise secured to the upper edges ofthe electrode plates 15. These rods' not only serve to support theelectrode plates but they also serve as circuit terminals for saidplates.' Intermediate adjacent chambers 12 and in the space within there- 'ceptacle outside of said chambers are suitably suspended andsupported the coperating electrode plates 17 having similar suspendingrods 18 passing through the top or lcover 11. Of course the rods 16, 18should be efficiently insulated from the top or cover 11 as-indicated at40, Fig. 1. The electrode arrangement is shown wherein the porousldiaphragms 19 are suspended from the eX- terlor surface of the loweredges of the walls 13 ofchambers 12.

In Fig. 3 a slightly modified arrangement` is shown wherein thetank 10is divided into two distinct and separate chambers 20, 21 by a wall l22,bent back and forth upon itself into parallel portions, said wall, inaccordance with my invention being formed integrally 'with the top orcover for the tank and depending from theunder side thereof downwardly'into the tank and immersed at its lower edge in the electrolyte. Theelectrodes 23, 24-,a're suspended-between the adjacent folds or parallelportions of the Wall 22 on opposite sides of said wall, that is',respectively, within the chambers 20, 21, said plates being suspended inthe manner above described, with reference to the plates 15, 17 of thearrangement shown in Figs. 1 and 2. It will be understood that theelectrode plates '15, -17 are connected to terminals of oppositesign ina supply circuit for a current of electricity. Similarly, electrodeplates 23, 24 of the arrangement shown in Fig. 3 are connected toterminals of opposite sign'. In the case of the arrangement showninFigs. 1 and 2, the gas evolved from plates 15 collects in the chambers12, which are in communication with each other, and from these chambersthe collected gas passes offy through any suitable delivery connectionssuch, for instance, as the lantern 27 and thence to asuitable gasometerand service pipes in a' well known manner. In like manner the gasevolved from electrode plates 17 ycollect in the top of the tank 10 inthe space outside of said chambers 12 from which said gas is deliveredin the ordinary or usual manner, as, for instance, through the vlantern27 and thence tothe gasfometer, receiving tank or service pipes in theusual way. Similarly in the arrangement shown in Fig. 3 the gas evolvedat the surface of electrode plates 23 collect in chamber 21 and isdelivered therefrom through pipe connection 28 while the gas evolved atthe surface of plates 24 collect in chamber 20 and pass off throughconnection indicated at 29.

Where the walls 13 or 22 are curved it may be inconvenient to applyorous da:

phragrn 19 to the inner arcs of tie curve of *said walls. In order toovercome this ob-l stacle various eXpedients may be employed as shown,for instance, in the arrangement shown vin Figs. 4 and 5, the curtain 19may be slitted as indicated at 30 so as to slip edgewise over the loweredge of the wall 13 so that the diaphragm may be applied to the'exterior surface ofthe Wall 13 at the ben-d thereof. This form ofconnection is also particularly applicable to the construction shown inFig. 3, asclearly indicated therein. Janother arrangement is showninFig.

6, wherein the curtain 19 is made in sections placed respectively on theoutside and inside surface ofthe wall 22, for instance, so as to'beapplied only to the convexed surface thereof, the adjacent edges of thesections of curtain passing somewhat beyond `each other and secured byclamp bolts and plates indicated at 31 applied thereto,

It will be understood that in the construction shown in Figs. 1 and 2 asmany chambers, 12, may be employed for each tank 10 as may be desired,according to the desired capacity or output thereof. While, therefore, Ihave shown only. two of such chambers, my invention is not to be'limited'or restricted in this respect.

From the foregoing description it will be seen that I provide anexceedingly simple, inexpensive and eiicient electrolytic cell iffmetete n l nin enabled to do away with exl and complicated pipeconnections and iittings, wherein the eell tank is 11min closed by e topor cover applied thereto, wherein the electrode plates are .maintainedin etlioient separation from each other :ind wherein intermingling otthe evolved gases is prevented.
